JOSEPH M. RIBERT, OF NEIf YORK, N. Y., ASSIGNOR TO NATIONAL NOV- ELTY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

COFFEE-MILL.

SPECIFICATION forming part of Letters Patent No. 786,151,`dated March 28, 1905.

Application filed October 5, 1904. Serial No. 227,263.

Be it known thatI, JOSEPH M. RIBERT, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Coffee-Mills, of which the following is a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in coffee-mills of that class in which the canister holding the unground coffee is attached to the mill proper and the receptacle tohold the ground coffee is removablyplaced upon a support attached to said mill proper.

The object of the present invention is to provide certain novel improvements in the construction of the mill proper whereby the cost is cheapened and the efficiency increased, to provide a novel means for securing the canister to the mill proper whereby breakage of the canister is less likely to occur than in the ordinary construction, and, finally, to provide certain novel arrangements for supporting the receptacles for the ground coffee whereby liability of breakage is avoided and facility in packing for transportation secured.

The invention therefore consists in the matters hereinafter described and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in whichm Figure l is a side elevation of the coffee-mill apparatus embodying my invention. Fig. 2 is a rear elevation, partly in section. Fig. 3 is a sectional view on the line 3 3 of Fig. Q.. Fig. 4 is a sectional view on the line 4 4 of Fig. F ig. 5 is a detail perspective of the receptacle-holding frame, and Fig. 6 is a detail view of the removable casting which forms part of the framework of the mill for supporting the guides for the receptacle-holding frame.

Referring to the drawings, the casing proper of the mill is made up of two parts, preferably castings A B, of which the portion A has a flat vertical center a, from which eX- tend rearwardly two legs or brackets b, terminating in feet provided with screw-holes by means of which they may be securely attached to a wall or other object. The portion B of the shell is provided with ears c, registering with ears (Z on the portion A, through which ears pass screw-bolts e to hold the parts securely together.

The portions A and B have upwardly-extending' vertical flanged portions O, having' an internal groove D, adapted to embrace a rib f in the bottom of the canister E. A washer or gasket beinginteri'iosed between the entireinlner surface of the fianges C and the outer surface of the lower neck F of the canister affords a firm clamping device for the canister, but prevents anyy liability of breakage, as would be likely to occur were no washer interposed or were there any bearing-surface at all of the metal flange on the neck of the canister.

The casting B has a central opening in which is journaled the shaft G of abur H, opposed to the shell A, between which and itself the coffee is ground. This shaft is actuated by a suitable handle I. The portion Bat its bottom has a semicircular iiange K,connected with the body of the portion B by the web L and is cut ont at /t to form a mouth for the channel e', through which the ground coffee passes out. The portion B also has cast with it the half-tubes 7u, which form, with the half-tubes Zon the casting M, secured by screw-bolt my passing through the portions B and A, guiding-lugs, as hereinafterdescribed. This casting M has a semicircular bottom plate N, forming, with the semicircular flange K on theI portion B of the coffee-mill, a top for the ground-coffee receptacle. It has an ear n, adapted to be secured to the wall or other object.

O represents the bottom of the receptacleholding frame, constructed with an upturned fiange 0 around a portion of its periphery, the open part p being' left to allow the glass or other receptacle P to slip in position readily.

Lugs q are provided on diametrically opposite sides of the plate O, and to these lugs are secured the lower ends of rods which extend into the tubes formed by the partsl Z and serve to support the holding-frame therefrom,

springs R keeping the rods and plate O normally raised to hold the glass or other receptacle P lirmly between the plate O and the flanges K M.

A washer/w prevents withdrawal of the rods from the guides.

When it is desired to pack the apparatus for transportation, the glass or receptacle IJ may be removed, and the rods Q, with the plate O, are 'forced upwardly, thus red ucing the length of the apparatus and permitting it to be packed in a limited space.

When it is desired to use the apparatus, the plate O is pulled down against the pressure ot' the springs R and the receptacle IJ inserted. When the frame is released, the receptacle is lirmly secured, ready to receive the material fed to it from the mill.

The simplicity and elfectiveness ofthe abovedescribed apparatus will be readily7 apparent, and while I am aware that coffee-mills embodying the same general features of construction are well known, yet the details ot' the present apparatus, whereby the results arrived at are accomplished, are believed to be new and patentable.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

l. 1n a coffee-mill or like device, the combination with the mill-casing proper having the vertical iange with internal groove, acanister having its neck provided with a rib registering with said groove, and an intermediate gasket or washer between the fiange and the said neck and covering said rib, and entirely preventing contact ot' the liange with the neck of the canister; substantially as described.

2. In a cofee-rnill or the like, the combination of the shell and vertical back plate, means for securing them together, the back plate and shell each having upwardly-projecting semicylindrical flanges with an internal groove forming between them a circular canister-supporting opening, said canister having its neck inclosed between said flanges and havinga rib, registering with the groove in the Hanges, and a gasket or washer intermediate the flange and canister-neck and entirely encircling the latter and covering` said rib; substantially as described.

8. In a coiiee-mill or the like, the combination of the shell and -the vertical back plate, means for securing said parts together around the canister-neck, and means for securing them to a wall or other object, and the removable casting attached to the shell and back plate and forming a portion otl the cover-plate for the ground-cofee-holding receptacle, and a spring-supported receptacle-holding frame; substantially as described.

4. In a coi'ee-mill or the like, the combination with the mill proper, carrying' the cover-A plate for the ground-cogee receptacle, a holding-frame for said receptacle, spring-supported from said mill proper, and adapted to clamp said receptacle firmly against the cover-plate, said holding-frame being slidable with respect to the mill proper to facilitate packing; substantially as described.

5. In a coffee-mill or the like, the combination with the mill proper, carrying the coverplate for the ground -coffee receptacle, the holding-frame for said receptacle having rods guided in lugs on the mill proper, springs acting upon said rods when they are withdrawn slightly to allow the placing of the receptacle on the frame, and means for permitting longitudinal movement of the rods, when the receptacle is removed to facilitate packing; substantially as described.

In testimony whereotl I aHX my signature in presence ot' two witnesses.
